300-515 Exam Question 36

Refer to the exhibit. IPv4 traffic between location A and location B has previously experienced no congestion or packet drops. The hub R3 router was recently added to the network and connected to R1 and R2 over Frame Relay T1. Link A has just gone down, and an engineer is observing congestion on both of the R3 connected links. Which change must the engineer make to the network topology to fix the issue and prevent such congestion if link A goes down again?

  • 300-515 Exam Question 37

    Refer to the exhibit. As their network ages and traffic increases, the network-engineering team at a small company is concerned that links may degrade in performance over time, which makes the degradation difficult to detect before becoming widespread. The team decided to implement Ethernet OAM to monitor links to certain critical resources, such as the file server.
    Which action must the team take so that remote OAM is alerted when a fault occurs?

    Tasks
    CE1 and CE2 are customer premise equipment of the same customer that communicates with each other over L2VPN provider infrastructure comprising Provide Edge PE1, PE2, and P core routers.
    Configure the PE routers to choose the configured Loopback 0 as its LDP identifier persistently.

    Troubleshoot the PEs to establish a complete MPLS LSP path between them.

    Troubleshoot and modify PE2 to ensure the configured L2VPN VC is up and passing traffic.

    Initial configuration with IPv6 addressing has been completed. The candidate must not make any changes to the configurations except to fulfill the tasks listed above. Apply the solution with the minimum config.
